A (generally) teen-age boy who spends the majority of his time masturbating into a tube sock. Sock fillers tend to be socially awkward, often standing slack-jawed while in the presence of their female classmates.
"As the girls' P.E. class ran past, a large number of sock fillers began to shift uncomfortably and mumble to each other."

saggy ass titties that could completely fill a knee-high tube sock...it was originated in africa when poor black ladies were unable to purchase a real bra....they ended up using socks and powerade bottles

Typical loser, shifty looking with a narrow neck.At home masturbating into his socks cos he’s too bone idle to go to the toilet for bog roll
‘Hey why’s Dave not in the pub tonight’ ? ‘He’s sick of getting blown out mate, he’s at home dragging one off to Love Island the sock filler’
